Phar::copy — Copy a file internal to the phar archive to another new file within the phar

### Beschreibung

public Phar::copy(string `$from`, string `$to`): true

> Hinweis:

> Diese Methode des Phar-Objekts funktioniert nur wenn die php.ini-Einstellung `phar.readonly` auf 0 gesetzt ist, sonst wird eine PharException geworfen.

Copy a file internal to the phar archive to another new file within the phar. This is an object-oriented alternative to using copy() with the phar stream wrapper.

### Parameter-Liste

`from`

`to`

### Rückgabewerte

Gibt immer `true` zurück.

### Fehler/Exceptions

Throws UnexpectedValueException if the source file does not exist, the destination file already exists, write access is disabled, opening either file fails, reading the source file fails, or a PharException if writing the changes to the phar fails.

### Beispiele

Beispiel #1 A Phar::copy() example

This example shows using Phar::copy() and the equivalent stream wrapper performance of the same thing. The primary difference between the two approaches is error handling. All Phar methods throw exceptions, whereas the stream wrapper uses trigger_error().

`<?php
try {
$phar = new Phar('myphar.phar');
$phar['a'] = 'hi';
$phar->copy('a', 'b');
echo $phar['b']; // Outputs "phar://myphar.phar/b"
} catch (Exception $e) {
// Handle error
}
// The stream wrapper equivalent of the above code.
// E_WARNING are triggered on error rather than exceptions
copy('phar://myphar.phar/a', 'phar//myphar.phar/c');
echo file_get_contents('phar://myphar.phar/c'); // Outputs "hi"
?>`
